This product is used on our fishing boat on the Saint Lawrence River. We damaged our last panel and needed a battery change. While the old device was rated at 5W, the new one has 8W, which is what we needed as we are now charging 2 batteries with the same panel. After 3 weeks of storm and bad weather, the batteries were fully charged although the bilge pump was running to keep the boat dry (there is no weather protection on the boat). We are so happy with this solar panel that we are going to get another one for the boat to keep the number 3 battery charged. The small size made it easy to mount on the radar arch and most people don't realize it's there. The only improvement I see for this device is a more streamlined panel mount frame, but that's purely cosmetic. Thank you for a great product at an attractive price, David J.
